Jeff Epler 9632360caa Use a macro to compute the size of arrays at compile time (#18044 ) * Add ARRAY_SIZE and CEILING utility macros * Apply a coccinelle patch to use ARRAY_SIZE * fix up some straggling items * Fix 'make test:secure' * Enhance ARRAY_SIZE macro to reject acting on pointers The previous definition would not produce a diagnostic for ``` int p; size_t num_elem = ARRAY_SIZE(p) ``` but the new one will. explicitly get definition of ARRAY_SIZE * Convert to ARRAY_SIZE when const is involved The following spatch finds additional instances where the array is const and the division is by the size of the type, not the size of the first element: ``` @ rule5a using "empty.iso" @ type T; const T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) @ rule6a using "empty.iso" @ type T; const T[] E; @@ - sizeof(E)/sizeof(T) + ARRAY_SIZE(E) ``` * New instances of ARRAY_SIZE added since initial spatch run * Use `ARRAY_SIZE` in docs (found by grep) * Manually use ARRAY_SIZE hs_set is expected to be the same size as uint16_t, though it's made of two 8-bit integers * Just like char, sizeof(uint8_t) is guaranteed to be 1 This is at least true on any plausible system where qmk is actually used. Per my understanding it's universally true, assuming that uint8_t exists: https://stackoverflow.com/questions/48655310/can-i-assume-that-sizeofuint8-t-1 * Run qmk-format on core C files touched in this branch Co-authored-by: Stefan Kerkmann <karlk90@pm.me>		2022-08-30 10:20:04 +02:00

Mitosis

A wireless split compact keyboard.

Keyboard Maintainer: @reversebias
Hardware Supported: Mitosis PCB
Hardware Availability: See the Mitosis keyboard announcement and discussion

Make example for this keyboard (after setting up your build environment):

make mitosis:default

See build environment setup then the make instructions for more information.

Notes

Some circuit board manufacturers including DirtyPCBs and PCBWay offer a steeply discounted "prototyping" rate for a small quantity of identical circuit boards less than 100x100mm in size. The Mitosis was designed to take advantage of this, so that individuals might affordably manufacture their own without waiting for a group-buy.

These configuration files were based off the Atreus keyboard. It assumes a Pro Micro is being used, however retains the 'make upload' feature from the Atreus branch.

This keyboard uses a completely different 'matrix scan' system than most other keyboards supported by QMK. Here, QMK runs in a Pro Micro on a receiver module, and communicates only with an nRF51822 microcontroller module that in turn does wireless communication. The nRF51822 maintains a matrix of keystates received from the same microcontrollers on each of the keyboard halves. The matrix.c file contains the code to make the Pro Micro poll the external wireless microcontroller for the key matrix. As long as this file is not changed, all other QMK features are supported.
